How to set up Deviation/ Slippage points / spreads in my signal subscriptions

 

Hi Just wondering how can I set up XAUUSD Deviation/ Slippage points / spreads in my signal subscriptions.

Due to can't copy the XAUUSD signal from my signal provider. I thought may be the spreads I set up only 3.0 Spreads

have any good suggestion? 

How can I set up the Deviation/ Slippage points/ Spreads.  If I want to follow the signal provider?
